Several tech moguls that were ranked in the top ten in 2010, such as Eric Schmidt, Steve Jobs, Larry Ellison, Evan Williams and Biz Stone, were omitted entirely from the 2011 edition; a few others, like Zuckerberg, Bezos and Ive, have made repeat appearances.

"Mark Zuckerberg, founder of the inescapable social-networking site Facebook, maintains his perch at the top of Vanity Fair’s 17th annual New Establishment List ranking for the second year in a row," writes Vanity Fair of the CEO, who was selected as TIME's person of the year in 2010. "With a possible I.P.O. on the horizon by 2012, which could value the company anywhere between $50 and $100 billion, Facebook has enough clout to worry even the unshakable Google. Zuckerberg is still the youngest person ever to top the list."

Zuckerberg has come a long way from the Harvard dropout who, in a 2005 interview, said of Facebook, "I still don't know if we have something."

"A lot of people are focused on taking over the world or doing the biggest thing and getting the most users," he added at the time. "I think part of making a difference and doing something cool is focusing intensely."
